Hi,
With recent ROOT, doing CMake failed when LLVM_ENABLE_SPHINX is enabled, as the following.
$ cmake -DLLVM_ENABLE_SPHINX=ON ../root.git/

Tracing the cmake process, AddSphinxTarget is include()d at least three times,
interpreter/llvm-project/clang/docs/CMakeLists.txt(104): include(AddSphinxTarget )
interpreter/llvm-project/llvm/docs/CMakeLists.txt(106): include(AddSphinxTarget )
interpreter/cling/docs/CMakeLists.txt(60): include(AddSphinxTarget )
but it seems the last one, for cling, is failing…
I couldn’t resolve the issue by myself and so just report…
Thanks,
Kazuyoshi
